Traps, of which the :followingis a specifical'lUll.

My invention relates to separator traps,

,3,0 and consist-s oi' improvements on that class ot trap which is shown and described in l'nited'St'ates Letters Patent No. LOOAB, `granted to me October 10, 1911. The separator trap shown and described in the said patent fulfils its purpose under all the usual conditions, but it has been found that when an abntu'mally .large quantity oi liquid is carried suddenly into the'trap, the agitation and oscillation of the liquid therein causes volatile. [luids to pass out of the trap through the outlet and also discharges an undesirable quantity ot water into the receptacle which,

under more normal conditions, receives only lighter fluid such as oil or gasolenc. The improvements herein described'are designed to lake'care ot' such emergencies and to insureA proper operation of the separator trap even though a very large quantity of liquid is charged into it suddenly.

The drawing hereto annexed represents, partly in section and partly in elevation, an apparatus embodying these improvements.

in this drawing thc trap bodv 1 comprises essentially the same functional elements as the trap body described in my said patent.

The upper part ot' the body is divided by the vertical partition 5 into two chambers;

a receiving chamber 2 which communicates with the inlet pipe 3, and the collecting 40 chamber l which receives the lighter fluids which arc carried into the trap with the water, Both top and bottom of the trap body are open, as at 6 and 7. The collecting chamber fi contains a partition or darn S which divides the collecting chamber into two portions at the lower part thereof and determines-the level ot outlet from the eollecting chamber; and from one oi these corn- ])arlments 10 issues the oil discharge pipe 9 which communicates with a receptacle 11.

The trap body 1 is inclosed'in a tank 12 which' is relatively much larger than the trap bodymy so that the bulk of water contained in the tank 12 is, as contrasted with the water contained in thc trap body l, a dominant mass. The outlet 16 issuing from the tank 12 is at proper level to maintain correct normal relations of water and oil levels Within the trap body l. Should a large quantity of liquid be charged into the trap' throughl the outlet 3,.the bulk of liquid standing in the tank 12 is so great that the disturbance produced by the entering liquid is absorbed and little oscillation ensues. 'Die collection ot light fluid such as oil or. gasolene in the receiving chamber 4 is temporarily raised sothat .u portion of it may rlow into the compartment A10. and thence out through thepipc 9. The outlet pipe 16 is formed. with an inverted dam or weirl( within the tank, so that the outlet pipe is' not in communication 'with the'upper por- 'tion' of the tank, which may contain 1nllanunable, gases 'from the evaporation of volatile luids. if the inrush of liquid tluioughthc inlet pipe S is so great as to splash over into the tank through the openn ingr G or to carry light volatile i'uids down through the body 1 and into the tank i', such volatile tluids 'Will rise to the surface of the liquid' in the'tank and there evaporating pass through the Vent 13 which preferably is continued to the root of the building so as to discharge out ot doors. The proportion ot the total cross sectional area oi the tank` 12 occupied by the inverted.

mouth of the outlet pipe 16 is so small that little, if any, volatile liquid will find its way into this outlet pipe. The revision of the inclosing tank 12 also furnishes convenient means for collecting and getting rid of sand or other grit and dirt which is likely to enter the trap. Solid material of thisI character collects at the bottom of the tank12, falling.

through the open bottom 7 of the trap body 1. An aperturc'll controlled by a suitablevalve 15 may he provided Wherewith oecasionally to discharge sand and other dirt from the. bottom of the ta'nlr.

I claim: l

1. ln a separator trap, the combination of a trap body open at ton and bottom .formed with a receiving chamber and a collecting chamber in the upper part ci thebody, an inlet to the receiving chamber, an outlet from the collecting chamber above the normal level of liquid in the tran, a partition between said chambers extending below said normal liquid level, a tank in which the trap body is ineloscd, an outlet for liquid from said tank, and a vent from the upper part of said tank.
